Weymann Keystone State Style #25 Mandolin Banjo , c. 1920

Weymann Keystone State # 25 Mandolin Banjo

Weymann Keystone State Style #25 Model Mandolin Banjo, c. 1920, made in Philadelphia, natural lacquer finish, maple neck and rim, black gig bag case.

A very nice "Small Pot" banjo-mandolin of the type popular in the late 1910's and early 1920's. While many of these were built on cheap spunover rims, this Weymann is beautifully crafted with a 5-ply maple rim, solid maple neck and dowel, bone nut and thick ebony fingerboard with small pearl dots, and original bar frets. Enclosed mandolin-style metal button tuners, and standard heavy Weymann hoop and hardware.

The dowel stick is very short and does not bear the usual Weymann style or serial numbers; these are marked on the top of the headstock. The elaborate neck adjusting brace is stamped with the patent number granted to Weymann around 1917. The original WEYMANN KEYSTONE STATE brand gold label has flaked off but the outline is clearly visible.

This is as high-quality an example of this particular type of instrument as one is likely to find, and a very nice playing and sounding little instrument.
Overall length is 22 3/4 in. (57.8 cm.), 7 in. (17.8 cm.) diameter head, and 2 1/4 in. (5.7 cm.) deep. Scale length is 13 1/2 in. (343 mm.).

Very clean original condition, with no repairs or major wear. All original components except bridge and possibly tailpiece, which is a 20's style covered "Grover PAT." type often seen on banjo-ukes. Set up with a vintage skin head marked "Three Star Quality"; plays fine. Excellent Condition.
